There are many cool bookmarklets out there that do cool things without an add-on installation. So many, in fact, it's easy to lose track and clutter your bookmarks. This Bookmarklet Combiner creates a master bookmarklet that can launch them all.

W-Shadow's web tool couldn't be more simple. Copy the JavaScript code from your bookmarklets (usually accomplished with a right-click, then "Edit" or "Properties"), paste them into the combiner field, then give them each a name. Choose whether you want a drop-down menu to appear with your bookmarklets listed, or fire a combination of bookmarklets all at once. Name your One Bookmarklet, drag it to your bookmarks, and you're done.

It's a free service, and worked with everything I threw at it. So what kind of bookmarklet combinations and aggregations can you suggest? Share your suggestions in the comments.
